Advances in 3D printing technology over the past decade have led to its expansion into all subfields of science, including chemistry. This technology provides useful teaching tools that facilitate communication of difficult chemical concepts to students and researchers. Presented here is the use of 3D printing technology to create tangible models…

Nearly all physics instructors recognize the instructional value of force diagrams, and this journal has published several collections of exercises to improve student skill in this area. Yet some instructors worry that too few students perceive the conceptual and problem-solving utility of force diagrams, and over recent years a rich variety of…

We have developed an easy-to-use online tutorial generator designed to allow instructors to make tutorials quickly and with a minimal learning curve. The motivation was to create a generator that would allow instructors to create tutorials as needed and possibly build up a bank of tutorials over a number of years. A key design feature of the…

Previous work has established that a narrated animation is more effective at communicating a complex biological process (signal transduction) than the equivalent graphic with figure legend. To my knowledge, no study has been done in any subject area on the effectiveness of animations versus graphics in the long-term retention of information, a…

Systems incorporating two advanced technologies, hypermedia systems and intelligent tutors, are examined with respect to their potential impact on science education. The conceptual framework underlying these systems is discussed first. Applications of systems are then presented with examples of each in operation within the context of science…

Discusses the role and activities of student tutors in an undergraduate organic chemistry course. Points out that such tutors must be used as a complement to the classroom lecturer, not as a substitute. (JN)

Discusses the various needs of chemistry classes in community colleges. Describes a tutorial package using computers. Reports the students' verbal evaluations and a drop in the dropout rate. (YP)

Reviewed is computer software on: (1) classification of living things, a tutorial program for grades 5-10; and (2) polynomial practice using tiles, a drill-and-practice program for algebra students. (MNS)

Discusses a research project that uses artificial intelligence techniques to help teach programing. Describes principles and implementation of the LISP Intelligent Tutoring System (LISPITS). Explains how the artificial intelligence technique was developed and possible future research. (MVL)

Reviews three software packages: (1) "Physics," tutorial, grades 11-12, Macintosh; (2) "Hands On Math: Volume I," interactive math exploration/simulation of manipulatives use, grades K-7, Apple II; and (3) "A.I.: An Experience with Artificial Intelligence," simulation, grades 5-12, Apple II. (MVL)
